HANGER FOR ELECTRIC LAMPS.

SPECIPICATION'forming part of Letters Patent No. 365,414, dated .run'ze,1887.

Application filed February 19. 1887; Serial No. 228,161. (No model.)Patented in Canada March 9, 1887, No. 26,180.

.To all whom, it may concern:

Be it known that I, FREDERICK THoMsoN, at present of the city ofMontreal, in the district of Montreal and Province of Quebec, Canada,have invented a certain new and useful Improved Hanger for ElectricLamps, (a patent for which has been granted in Canada, No. 26,180, March9, 1887,) and I do hereby declare that the following is a full, clear,and exact description of the same.

My invention has reference to the supports of electric-aro lamps inwhich the carbons must be renewed and readjusted, and is intended to doaway with the necessity of lowering such lamps for the above purposes.

I propose to secure to the post or other vertical support a doublebracket, the upper arm of which is horizontal and the lower curved orbent, so as to form a seat or restingplace for the trimmer. In the endsof this double bracket are formed eyes, through which passes thepivot-pin of a-swinging bracket, carrying on one end the lamp and on theother a counterpoise. This arrangement allows the lamp to be easilyswung in within reach of the trimmer.- The connectingwires to the lampare carried on horizontal cross-arms supported one on the fixed and theother on the swinging bracket, there being an extra length of linebetween these two, so as to avoid any strain on the connections inswinging the ex-.

tension-bracket out or in. To either the fixed or swinging bracket issecured a link, hook, or stop to prevent the extension-bracket fromswinging round.

In a short hanger, or one with little projection, the counterpoise maybe omitted, the depth of the bracket being slightly increased. For fullcomprehension, however, of the invention, reference must be had to theannexed drawings, forming part of this specification, in which- Figure 1is a View of my hanger attached to an electric-light pole with extensionswung out; Fig. 2, a similar view with extension swung in, and Fig. 3 aview of modification of hanger.

Similar letters of reference indicate like parts. y

A Aare the arms forming the fixed bracket, projecting any distancerequired and being usuallyforked from about the points marked,-

C is the electric lamp secured on one end of B, and D a counterpoisemounted on an extension of the opposite end.

Connection is made from the main wires of the circuit to the poles ofthe lamp by the wiresE E,-carried on the cross-arn1s F, F, and F thefirst of these being carried on an upright, cl, forming part of B, thesecond, F, on

anupright, d, passing down through and secured to the fixed bracket, andthe third, F, beingseeured in the usual way to the pole. The upright (1'acts as a brace for connecting the brackets A A, and will also serve asa stop toprevent the bracket B from being swung too far round.

In themodification shown in Fig. 3, and which is applicable where thehanger is required to project but a small distance, comparatively, theoracketB is somewhat differently framed and the counterpoise dispensedwith, the pivot-pin B carrying the cross-piece F, and another verticalpiece, B being provided as a brace and stop. I) is a link or catch forlocking the swinging bracket in position.

It will be seenthat the trimmer, having mounted to the height of thebracket, can, by turning up the hook a or other locking device, swingthe lamp in within easy reach and replace the carbons, or do anyadjustment necessary, and that the necessity of lowering the lamp forthese purposes is entirely done away with. i

Although the invention is shown as applied to an electric-light pole, itis obvious that by a slight modification of the fastenings of the fixedbracket any other support will serve.

I am aware of the Patent N 0. 314,976, granted 011 the 31st March, 1886,to W. H. OBeirne, and also of Patent No. 347,830, granted to J. J.Renehan, on 24th August, 1886, and No. 348,845, granted to C. C.Haskins, dated the 7th September, 1886; but in all these the hangerv ispivoted so as to allow the outer end,or the one carrying thelamp, to belowered, which construction I disclaim.

hat I claim is as follows:

1. A hanger for an electric lamp, consisting of a bracket fixed to asupport, an arm forming an extension of same and carrying the lampalways at the same height, and a vertical pivot-pin on which said lampis swung in and out on the same. horizontal plane.

2. The combination, in an electric-lamp hanger, of a bracket fixed to asupport, an extension-bracket swinging horizontally on a pivot andcarrying on one end the lamp and on the other a counterpoise, allsubstantially as herein set forth.

3. In an elcctric-lamp hangelgafixed bracket carrying a pivotedextension and formed of an upper straight arm and a lower bent arm, bothforked and having their ends curved so as to fit the pole, all as hereinset forth.

4. The combination, in an electric-lamp hanger, of a bracket secured toa support, a horizontal swinging extension of same, and a catch on saidbracket to hold extension, all as and for the purposes set forth.
